A Fall wedding for an Autumn posting! 
Letterpress has become all about impression.  Not just the impression on the guest receiving the invitation, but the actual plate impression into the paper.  Printing with ink does show this off, but blind impressions play with the press in an entirely different way.  Really digging into the paper, allowing the light and shadow to present the image...it's graceful, beathtaking and unique to letterpress. 
Amy Cooper's invitation features blind impression at its best.  The 6x9 invitation is our 2 ply museum board, fast becoming my absolute fav.!  With eggplant and sweet pea inks throughout, the blind press becomes an eye-catching accent.  Using the blind impression on the belly band creates a soft, textured element that doesn't take away from the beautiful invitation beneath.  The belly band is also function of course - all of the insert pieces could be held to the back of the invite under the band. 

In the end, blind press gives the invite that "oohhh" element and every guest will surely run their fingers over the impression.
